Some more general ones...
Smyth: I did not expect that realism that people were raving about, but this is the real deal. I briefly sat down at Beyer and did their little head motion thing... a toy compared to Smyth's stuff.
HF-2: a little extra bass oomph, but very good balance. Preferred it over HF-1 and RS-1. Nick Drake's Fruit Tree (acoustic folk) sounded incredible.
Shure headphones: The highest model SHP840 was rather nice and not too closed sounding, comfy, and solid. The lowest 240 model is bad.
L3000: Just not my thing. Sounded artificial.
D5000: Definitely not my thing. Weird, boomy, bland, something.
Monster Beats: lol.
sources and amps: everything sounded good to me, but I don't recall using anything outside of the usual good HeadAmp, HeadRoom, DIY stuff. Lots of nice upstream components at the meet.
I also expect cetoole's C-2C impressions... lucky bastard
